Google Search 3.5.14 is slowly but surely rolling out right now, with a few enhancements. Google will be allowing users to say “OK, Google”, the famous hotword from anywhere on the phone, to trigger a voice search. This means that instead of having to use that command in the homescreen, you can use it anywhere else.

The update allows you to trigger an “OK, Google” from the lockscreen for example and people who tested it (like in the video below) were happy with the feature. In order to turn on the new hotword detection, you need to enter Google Now, scroll to the bottom, tap Menu, then Settings, then Voice and OK Google Detection. There will you find the toggle for the options you need.

The app also brings Audio History as a new feature, with the function being just like the name says, an option to use voice searches to create a history that can make your searches more accurate. It can also learn your voice sound, pronounciation and more patterns. Have a go at this download link and see if the update has come.
